EDWARD E. BISHOP, OF LITTLETON, NEW HAMPSHIRE.

INCUBATOR.

. SPECIFICATION forming part of Letters Patent No. 245,121, dated August 2, 1881.

- Application filed August 21,1880. (Model.) l l Be it known that I, EDWARD E. BISHOP, of Littleton, in the county of Grai'ton and State of New Hampshire, have invented a new and Improved Incubator, of which the following is a specification.

The object ot' this invention isto construct an incubator that will operate with a maximum ot' efliciency and economy.

Figure 1 is a sectional side elevation of the incubator on'line u zeilig. 2. Fig. 2 is a sectional plan viewl on line x x, Fig. l. Fig. 3 is asectional plan view on line y y, Fig. 1. Fig. 4 is a sectional plan view on line z z, Fig. 1. Fig.5 is a vertical sectional elevation on line v t, Fig. 1. Fig. Gis a vertical sectional elevation 'on line w w, Fig. 1. Fig. 7 is an elevation of the boiler.

In the drawings, A represents the outer case of the incubator lined with some non-conducting material, preferably with rootingpaper secured with tacks.

In the front of the case A is a door, a,whieh opensfrom the egg-chamber B, that is located in the bottom of said case A, and is lined or covered on the outside preferably with building-paper.l lThe door B of said egg-chamber B is made to slope toward the door a, so that carbonio acid or other heavy gases generated within said chamber B may readily ow out when said door a. is opened, and thereby pre vent the air in said chamber from becoming or remaining impure.

C is the egg-drawer, provided with a wovenwre bottom,'c, set within the egg-chamber B, for holding` the eggs to be hatched.

Above the egg-chamber B is the main tank D, for containing hot water for maintaining a suitable temperature within the egg-chamber B. This tank D is provided with partitions d d, that `are designed to make the water flow evenly over the entire surface of the said tank D. The water in this tank D is designed 'to be kept at a depth of three inches, or more, so that the temperature in the incubator shall not be aiectedl by sudden changes of temperature.

Between the egg-chamber B and tank I) and the case A isA an airspace, f.

Outside the case A, secured on a suitable support, g, is a boiler, E, having a cover, g', that is removed for lling said boiler, and having a concave bottom, as shown at g, that the heating-surface ot the boiler may be thereby increased.

' Beneath the boiler E is a lamp-rest, F, on which is placed a lamp, (shown in'dottfed lines Vat 14",) for heating the water in said boiler E,

andthe boiler-support g, which is a broad plate of corrugated metal extending upward from the lamp-rest I", serves to prevent the flame of' the lamp I1l from burning the case A.

The main tank I), before described, is suppliedv with hot water from the boiler E through a pipe, h, leading from the upper part of said boiler E, and the water, after traversing said tank D, returns to the lower part of the boiler A E through the pipe h', whereby a constant eirculation of heated water is maintained. A pipe, It', designed for t-he insertion ot' a thermometer, whereby to determine the temperature of the tank D, extends upward from said tank through the top of the case A.

The air space or chamber j' around the tank D and egg-chamber B is kept at a suitable temperature by the hotwater pipe h, that enters said chamber f from the upper part of the boiler E, and, making a circuit ot said chamber f, returns to the lower part of said boiler E.

From the top of the egg-chamber B venti lating-pipes 7o extend upward at the sides of the tank D, through the top of the case A.

Attached to one end'of the case A, and forming part of the incubator, are certain auxiliary parts,consistingof awater or moisture pan,G,

extending the whole width of the incubator,

and supplied with water from an attached supply-tank, G', through a pipe, l, that extends above said pan G nearly to its opposite end. Pipe l also extends above the open ends of horizontal pipes n, which pipes commence in the casing above pan G and extend into the interior ot' egg-chamber B. In bottom ol' pipe l, and exactly above each one of the pipes n, is an orifice to allow the water to drop in front of pipes n, so as to more thoroughly mosten the air 5 and in the bottom of this pan G is a raised tube, l' ,for the escape of the water, when IOO easily removed and replaced. In the front of the casing of said pan Ci are a series of criticos, mf, that are designed to admit air that passes over the water in the pan G, and through the pipes n into the egg-chamber B, supplying moisture to the eggs therein, and thence passes through the ventilating-pipes it into the open air. This arrangement or' the water or moisture pan Goutside of the incubator proper prevents, in a great measure, the warping to which wooden incubators are liable, and from this pan G there is supplied moisture suflicientfor the eggs until theyarerelnoved from the chamber B to the drier-drawer I, where they must be sprinkled.

Immediately above the water-pan G is a drier'drawer, ],having on its top a wire screen, I', which screen is designed to receive eggs which are placed there to be warmed before being placed in the chamber B, which is very desirable when fresh eggs are everydayor two placed in the chamber B. This drawer I is designed also to receive eggs that are within two or three days of being hatched, as it is very injurious to other eggs to have chicks hatched and dried olic in contact with them. Consequently this drawer I increases materially the capacity and effectiveness of the incubator. This drawer I rests upon a removable board, o, which board is provided with suitable rests, and can be easily removed for the purpose ol' being cleaned.

Above the drawer I is the tank K for warniing Said drawer I. Said tank K is supplied with a circulation of hot water from the main tank I) by means ofthe pipes p p",through the latterotwhich the waterllows into, and through the former of which the water flows from, said tank K. The casing of said tank and drawer is provided with perforations t and s, register ing with perforations t in tank and s in drier drawer, respectively, for the purpose of venti lation. The tank K is stationary, and is to be reached by removing the top of its casing.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. In an incubator, an egg-chamber, B, having drawer C, and provided with horizontal moisture-communicatin g pipes n, and vertical `v'entilating-pipes 7c', substantially as shown and described, and for the purpose set forth.

2. In an incubator, the auxiliary hot-water tank K, having perforation t', registering with perforations t in casing, and parallel pipes p and p, i'or receiving and discharging hot water, respectively, in combination with the main tank D, substantially as shown andv described.

3. In au incubator, a moisture-pan, G, having tube i in its bottoni, in combination with chamber B, having moisturepipes a and velitilatingwpipes 7c', substantially as shown and described, and for the purpose set forth.

4. In an incubator, the reservoir G', having pipe l, in combination with pan G and pipes n, said pipe i extending above the ends ot pipes n, and having pertorations underneath for allowing water to drop in front of' said ori fices, substantially as and for the purpose set forth.`
